Abstract

A 37-core optical fiber with 14 air holes is proposed in this paper. This optical fiber can transmit the fundamental mode and part of the second mode. Effects of structure parameters on effective refractive index, bending loss and effective area of the fundamental mode HE₁₁ and the second-order mode HE₂₁ are investigated systematically. By adjusting the structure parameters, at wavelength of 1550 nm and bending radius of 5 cm, the effective mode field area of the fundamental mode is 1776.289 μm² , and the bending loss is 4.656×10^-5 dB/m. Due to the flexibility of multi-core structure, it is significant for theoretical research and practical manufacturing.
